[Computer-go] Parallela and Computer Go

2012-10-24 Thread Petr Baudis
Hi! There is a new fairly exciting parallelization platform in the works, currently as a kickstarter project (that will unfortunately likely not make it since while it's technically awesome, its marketing/PR campaign was far from stellar, but if you like it, don't hesitate to pledge in the

Hi! I saw this too, but the cores are ARM A9. With oakfoam one such core does 150 playouts / second on 19x19 (iPad1 with NiceGo, the free version of oakfoam for iPad), one i7-2600 core is more than 8 times faster. Even with good scaling a 64 core machine is only twice as fast as a i7-2600 I

Even if it is not terribly powerful per core, it could in theory allow for more people to cheaply do scaling tests and experiment with different algorithms to see how they behave as the number of cores increases (assuming there are not some architecture limitations in the hardware design

Yah, the starter kit has t small memories both on board and on the chip. I believe Xeon Phi, or Knight Corner, is much more practical, though far expensive. One interesting feature of Knight Corner is the 512-bit register file which can have bitmaps of 19x19 board. Hideki Petr Baudis:
